Did you click on the troubleshooting info link in response 2 and READ the info there ?
The led blinking all the time MAY indicate that you did NOT have it plugged into a USB port that can actually supply 500 ma of current.
"I took external caddy apart and connected to pc."....." The 1 TB WD external hard disk is only purchased 6 months back."
You have voided the drive's warranty by opening up the external drive.
It probably has a 1 year warranty.
" i didn't drop it ever. "
If ANYONE has had physical access to the eternal drive other than you, they could have dropped it and NOT told you about that.
Connecting the external enclosure without the hard drive being installed in it is relatively useless. The external enclosure (recognition of it's circuits) DOES NOT show up as a drive in Computer or Windows Explorer or in Disk Management.
If it IS being detected properly, it only shows up generically in Device Manager
under USB Controllers
- as a Mass Storage Device
- under one of the Root Hubs, problem one or the last ones listed, when you click on the Power tab, as a USB Mass Storage device that is drawing a small amount of current, e.g. 2 ma.
The hard drive that was inside the external enclosure is probably a SATA hard drive.
All SATA hard drives, 2.5" (laptop sized) or 3.5" (desktop sized) , have identical SATA data and power sockets on one end of the drive.
It can be connected to any desktop computer that has a mboard with a spare SATA data header with a standard SATA data cable, and a spare SATA power connector from the power supply.
If you connect your hard drive to a computer with a working operating system without disconnecting the hard drive that has that computer's operatin system on it, you can check out your hard drive to see if it is working properly and whether you can see the data is still on it, but you DO NOT boot the other computer from your hard drive.
When I look on the Western Digitral web site, there is NO info about a blinking led on one of their external drives.
When I searched for info on the web, e.g. using western digital external hard drive blinks led
there are MANY "hits"
The indicator LED is steady white when the drive is powered on but idle, and blinks off and back on when the drive is being accessed.
So - it's normal for that led to blik when it's being accessed, but it's NOT normal for it blink at a constant rate all the time
There are MANY hits that indicate other people are having the same problem with their e western dogital external hard drive as you are - the led is blinking at a constant rate not matter what they try.
That MAY indicate there is a problem with the circuitry of the external enclosure, but you can't make a waarantyu clain because you have opened up the external enclosure.
It's likely that if you replace the external encliosure with a new one, the hard drive you already have that was in it will probably work fine.
